BALL-BEARING.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed February 17, 1919. Serial No. 277,475.

To all who/7t it may concern:

Be it known that I, Tnnooonh HnenLitAN, a subject of the German Empire flv, ohas declared his intention of becoming. a has made United tates,) residing at ()a Park, in t e county of Cook and State of; llinois have invented new and useful Improvements in of which the following is a full, clear, and exact description;

My invention relates to improvements in ball-bearings, and particularly to the bear ings of loose pulleys and? transmission shafts.

An object of my invention is to to construct such ball-hearing that all the parts thereof are standard parts and. when any of said parts become damaged; can be removed and replaced without affecting the other parts. Another object is to enable such parts to be made in an economical,manner and to be easily and quickly assembled or This I uccm Ip'iSh by the means hereinafter described, and as particularly pointed out in the claims.

In the drawings:

Figure 1 is a longitudinal section of the boss of a wheel showing the application thereto of my improved ball bearing.

'Fig. 2 is a transverse section of the same taken on dotted line 2-2, Fig 1.

F ig. 3 shows an end view of one of the sleeves and a transverse section of the shaft to which the some is clamped.

Referring to the drawings, A represents a shaft and B the hollow circumferential shell of the boss of a loose pulley. In the event of my improvements being used for shaft bearings the shell of the cusim would be constructed ust the same as StlhfbOSS minus the arms rm iuting therefrom and plus some means for attaching; the same in a stationary position to a suitable support.

The ends of shell Bare closed bysnitable heads C, C, that are secured thereto by countersunk screws 0, c, and are provided with central openings Z), I), through which shaft A extends, and with suitable packing a, a;

in such openings. 7

At its center of length the interior of shell A is provided with an inte ral circumferential rib I), the transverse sldes of which are;

"preferably, disposed at right angles to the axis of the shaft.

Between heads'C, (J, and the central portion of the interior of the casing, shaft A has correspondin sleeves E, E, mounted thereon that are sp it longilonlgltudinall' tween flanges d, d, of

,pins J, J; which "suitablelongitudinal openings in flanges (l their heads enter suitable recesses in the side edges of ti e rings. and their tudinally on one side, and when assenwu the parts of the bearing, they are'slippe over the ends. of said Shaft an pushed engthwise thereoninw The ends of such sleeves neagestfheads U, U, are provided with cireiftnferential flan d, d, that have niches'e', e; out in their c rcumferences on one'side of the split to permit screws f, f, to be screwed in a tangential direction to draw the split edges of the sleeve together and securely clamp the same shaft aguinstlongitudinal movement.

The outer races F of my improvement consists of a list metal ringgthe outer cir cumferonce of which con ponds to the inner circumference of casng B within which it is plaeechand the inner circumferonce of which has'the usual circumferential groove therein in which he bearing-balls G, (i, travel. The inner wees H, H; also consist of flat metal rings of the same trans on the verse dimensions as the outer .l aces and the diameter of the inner ciroumierence' of these inner races correspond to tlfatof the outer and their width,

circumference of sleeve E, preferably, corresponds to the distane besleeves E and the op )osite ends thereof.

flhe races and circular cages I in which the ln aringi bails are retained are made in semi-circular sections and are mounted upon said sleeves between the flanges and the opposite ends of the same and are shoved into the casing, therewith at the same time and until they come in contact with rib D.

The inner races are, preferabl prevented from revolving u on'sleeves E iy means of utter are inserted through and have s I), outer ends swaged, as she 11. When nil the parts of my im roved ball-bearing are iro 'erly assemble, the inner race's are*he (1 against flung, s d (if the sleeve by the contact of the outer raoes with the rib and the outer races are held against the rib b the some ofthe inner races against the anges. T

inner and outevraces with the beil-ring balls between them, fill the space between the sleeves and the inner circumference-of the casing, and are locked in this position simply by clamping: the sleeves in dponition.

1 it is desired to remove replttoe ltn e l berets e of the parts of my: im that ,it IS necessary to p tes-- IQIS race, bearing-balls interposed between said races, a casing through which said shaft extends having a. circumferential rib projecting from its inner circumference, and means for keeping said outer race bearing against said rib.

2. The combination with a shaft, two sleeves mounted thereon, and an inner race mounted and retained on each sleeve, of an outer race concentric with each inner race, bearing-balls interposed between said inner and outer races, a casing through which said shaft extends having a circumferential rib mediate its ends, and means for keeping said outer races in contact with said rib.

3. The combination with a shaft, two sleeves mounted thereon that have their outer ends flanged, and inner races mounted and retained on each sleeve in contact with its flanged end, of an outer race concentric with each inner race, bearing-balls interposed between said inner and outer races, and a casing through which said shaft extends havirig a circumferential rib mediate its ends with which said outer races are in contact.

4. The combination with a shaft, two sep arated sleeves mounted and retained against longitudinal movement thereon, that have flanges on their outer ends, and an inner race mounted and retained against min pendent longitudinal movement on each sleeve, of a casin through which 'said shaft extends, separate outer races placed against the inner circumference of said casing, and means for preventing said outer races from moving toward each other.

The combination with a shaft, two sep aralcd sleeves mounted and retained against longitudinal movement thereon that have flanges on their outer ends, and an inner race mounted and retained against independent longitudinal movement on each slcevc, of a casing through which said shaft extends,separated outer races placed against the inner circumference of said casing, and

means integral with said casing for preventing, said outer races from moving toward each other. I

6. The combination with a shaft, two separated sleeves mounted and retained against longitudinal movement thereon that have flanges on their outer ends, and an inner rare mounted and retained against inde pendent. longitudinal movement on each sleeve, of a casing through which said shaft extends,separated outer races placed against the inner circmnfcrem-e .of said casing. and means interposed betwecn said outer races to prevent them from moving toward each other.

7. The combination with a shaft, a sleeve mounted thereon having its outer end flanged, an inner racc mounted and retained on said sleeve in contact. with said flange, and a pin extending through said flange and having its inner end enter a niche in the adjacent edge of said inner race, of an outer race, hearing-balls interposed between said inner and outer races, a casing through which said shaft extends, and means engaged by said outer race to prevent it moving longitudinally.

In witness whereof I have hereunto set my hand this 18th day of January, 1919.
